So, both of the following are issues, right?

1. parser doesn't accept syntax "-p=NAME", but only "-pNAME"

2. generated help text suggests otherwise, that the former is accepted

IMO, #1 is standard, but #2 is possibly the wrong behavior.

What is causing the difference between typical output and this case? Do 
you see the "-p --long=NAME" variant for other options in the same 
program? Looking at comparable output in my own use of optparse, the 
format tends to look like this:

     -r, --read-options [FILE]        Read options from file [stdin]
